1 Introduction

This document describes the level of support provided by Microsoft Edge for the Encrypted Media Extensions specification [W3C-EME], published 18 September 2017. The [W3C-EME] recommendation extends the HTMLMediaElement interface specified in [W3C-HTML51]. It defines an API to control playback of encrypted content, supporting use cases ranging from simple clear key decryption to high value video (given an appropriate user agent implementation). License/key exchange is controlled by the application, facilitating the development of robust playback applications that support a variety of content decryption and protection technologies.
